Step-by-step explanation:
Number of revolutions made by wheel
[tex] = \frac{distance \: travelled}{circumference \: of \: wheel} \\ \\ = \frac{704}{2\pi \: r} \\ \\ = \frac{704}{2 \times \frac{22}{7} \times 28} \\ \\ = \frac{704}{2 \times 22 \times 4} \\ \\ = \frac{704}{176} \\ \\ = 4 \\ [/tex]
Hence the wheel will make 4 revolutions.
